Question
How does temperature usually affect the solubility of a solid in water? (1 point)
Responses

High temperatures decrease solubility because ions have too much energy to come close and form bonds.

High temperatures increase solubility because ions have too much energy to come close and form bonds.
High temperatures increase solubility because ions have too much energy to come close and form bonds.

High temperatures increase solubility because ions do not have enough energy to come close and form bonds.
High temperatures increase solubility because ions do not have enough energy to come close and form bonds.

High temperatures decrease solubility because ions do not have enough energy to come close and form bonds.

Answer 1

The correct response is:

High temperatures increase solubility because ions have too much energy to come close and form bonds.

In general, for most solid solutes, increasing the temperature usually increases their solubility in water. This is because the added energy at higher temperatures helps to break the intermolecular forces holding the solid together, allowing more solute to dissolve.
